For measurement of kinematic viscosity of transparent and opaque Newtonian liquids. The Viscosimeter is also used to measure kinematic viscosity of cutback asphalts and road oils at 140°F (60°C) and asphalt cements at 275°F (135°C) in the range of 30 to 6000 centistokes. Can be filled and cleaned while in constant temperature bath. Minimum sample volume 1 to 3 ml. Required liquid bath depth of 230 mm (9"). All measurements are calibrated (precision ±0.3%). Supplied with permanently attached round metal holder, for hole 51 mm (2") in diameter. Certificate of calibration and instruction sheet provided.
